Description

Technical Field

[0001] This invention relates to the field of belt conveyor anti-deviation technology, specifically a hyperbolic drum damper for preventing belt deviation in coal conveying. Background Technology

[0002] Belt conveyor is a common material transport method widely used in coal mines, thermal power plants, and industrial production. It transports coal from one location to another via a conveyor belt. Typically, it relies on an electric motor to drive the drums to move the belt. It can continuously and quickly transport large quantities of coal. Compared to other transport methods, it has lower maintenance costs, and the conveying route and angle can be adjusted according to the site and requirements.

[0003] In the production processes of industries such as thermal power plants and coal mines, belt conveyors are used to transport raw coal over long distances. During the long-distance transportation of raw coal, belt misalignment and coal spillage often occur. When the misalignment is severe, it can cause belt damage or equipment failure, and even safety accidents. This not only pollutes the production environment, but also poses risks to the personal safety of workers and creates safety hazards for safe production.

[0004] Therefore, we propose a hyperbolic drum damper for preventing belt misalignment in coal conveying, in order to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a hyperbolic drum damper for preventing belt misalignment in coal conveying, so as to solve the problems of coal spillage, environmental pollution and unsafe incidents caused by belt misalignment as mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hyperbolic roller damper for preventing belt misalignment in coal conveying, comprising an anti-misalignment structure, wherein the anti-misalignment structure comprises a base and an mounting hole opened at the top of the base, a fixing component is welded and installed inside the base, a moving component is slidably installed inside the fixing component, and a bearing component is installed on one side of the top of the moving component.

[0007] The load-bearing component includes a connecting rod and a mounting rod installed on the outer surface of the connecting rod.

The middle ends of support plate A and support plate B are provided with mounting threaded holes. One end of the connecting rod is equipped with an internal threaded ring, which is located between support plate A and support plate B. The internal threaded ring is aligned with the mounting threaded hole, and a fixing bolt is used to connect the internal thread of the internal threaded ring to the mounting threaded hole.

[0009] Preferably, a mounting post is inserted between the bearing and the hyperbolic roller.

[0013] Preferably, observation slots B are provided on both sides of the lower end of the movable frame, and the width of observation slot B is greater than the width of observation slot A.

[0014] Preferably, the outer surface of the fixed frame is provided with threaded holes A on both sides away from the observation groove A, and the outer surface of the movable frame is provided with threaded holes B on both sides away from the observation groove B.

[0019] 1. The present invention discloses a hyperbolic drum damper for preventing belt misalignment in coal conveying. The internal threaded ring of the hyperbolic drum and one end of the connecting rod is located between support plate A and support plate B. After the internal threaded ring is aligned with the installation threaded hole, it is fixedly installed by fixing bolts. After the angle is adjusted appropriately, it is tightened.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figures 1-4 A hyperbolic roller damper for preventing belt misalignment in coal conveying includes an anti-misalignment structure 1.

[0029] The load-bearing component 15 includes a connecting rod 152 and a mounting rod 153 mounted on the outer surface of the connecting rod 152. A hyperbolic roller 156 is mounted on the outer side of the mounting rod 153. Bearings 154 are installed between the inner ends of the hyperbolic roller 156 and the two ends of the mounting rod 153.

[0030] A mounting post 155 is inserted between the bearing 154 and the hyperbolic roller 156.

[0031] The movable component 14 includes a movable frame 141. Support plates A144 and B145 are respectively installed on the top two sides of the movable frame 141. The middle of the support plates A144 and B145 are provided with a threaded hole 146. One end of the connecting rod 152 is provided with an internal threaded ring 151. The internal threaded ring 151 is located between the support plates A144 and B145 and is aligned with the threaded hole 146. The internal threaded ring 151 and the threaded hole 146 are connected by a fixing bolt 16. The fixing bolt 16 connects the internal threaded ring 151 to the support plates A144 and B145, which facilitates the installation of the load-bearing component 15.

[0032] The outer surface of the hyperbolic roller 156 is equipped with an anti-slip layer 158, which increases the friction between the load-bearing component 15 and the belt.

[0033] One end of the connecting rod 152 is equipped with an installation sleeve 157, which is used to constrain the position of the installation rod 153.

[0034] The fixing component 13 includes a fixing frame 131, and observation slots A132 are provided at both ends of the fixing frame 131, through which the internal condition of the fixing frame 131 can be observed.

[0035] The lower ends of the movable frame 141 are provided with observation slots B142 on both sides, and the width of the observation slots B142 is greater than the width of the observation slots A132. When the movable frame 141 moves inside the fixed frame 131, it is convenient for the operator to observe the use of the anti-deviation structure 1.

[0036] The outer surface of the fixed frame 131 is provided with threaded holes A133 on both sides away from the observation groove A132, and the outer surface of the movable frame 141 is provided with threaded holes B143 on both sides away from the observation groove B142.

[0037] The threaded hole B143 is aligned with the threaded hole A133. The internal threads of the threaded hole B143 and the threaded hole A133 are connected by an adjusting bolt 17, which is used to fix the moving frame 141 and the fixed frame 131 after the movement.

[0038] In this embodiment: the base 11 is fixedly connected to the coal conveyor belt steel frame with bolts or welded, the fixed frame 131 is fixedly installed to the base 11 by welding, the movable frame 141 is installed in the fixed frame 131 and fixedly installed with fixing bolts 16. After adjusting the height appropriately, it is tightened. The internal threaded ring 151 at one end of the hyperbolic roller 156 and the connecting rod 152 is located between the support plate A144 and the support plate B145. After the internal threaded ring 151 is aligned with the installation threaded hole 146, it is fixedly installed with fixing bolts 16. After adjusting the angle appropriately, it is tightened. This effectively prevents the belt from running off-center, reduces the possibility of coal spillage from the belt and belt damage, equipment failure, and safety accidents caused by severe belt running off-center. It also reduces pollution of the production environment, reduces the personal safety risks of workers and equipment safety hazards. This device has a small investment, a mature and simple structure, a short modification cycle, and quick results, and has good market and economic value.

[0039] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 4 and Figure 5 Both ends of the hyperbolic roller 156 are provided with injection holes 1561, and a transverse connecting hole 1562 is provided between the two sets of injection holes 1561 and inside the body of the hyperbolic roller 156.

[0040] Lubrication holes 1563 are provided on the inner walls of the transverse connection hole 1562 and the injection hole 1561 on the side facing the mounting rod 153. Lubricating oil is used to lubricate the mounting rod 153 and the connecting rod 152 through the injection hole 1561, the transverse connection hole 1562 and the lubrication hole 1563.

[0041] In this embodiment: Lubricating oil is injected into the injection hole 1561. Since the position of the transverse connecting hole 1562 is lower than that of the injection hole 1561, the lubricating oil flows into the interior of the transverse connecting hole 1562 due to gravity. A lubrication hole 1563 is provided on the inner side of the hyperbolic roller 156 and the side near the mounting rod 153. When the bearing member 15 rotates, the lubricating oil inside the transverse connecting hole 1562 flows to the outer surface of the mounting rod 153. The lubricating oil lubricates the connecting rod 152 and the mounting rod 153 through the gaps on the surface of the mounting rod 153, which facilitates the rotation of the mounting rod 153 and the hyperbolic roller 156.

[0042] Working principle: The internal threaded ring 151 at one end of the hyperbolic roller 156 and connecting rod 152 is located between support plate A144 and support plate B145. After the internal threaded ring 151 is aligned with the mounting threaded hole 146, it is fixedly installed with fixing bolts 16. After the angle is adjusted appropriately, it is tightened. This effectively prevents belt deviation, reduces the possibility of coal spillage from the belt and belt damage, equipment failure, and safety accidents caused by severe deviation. It also reduces pollution of the production environment and lowers the personal safety risks to workers and equipment safety hazards.
